Description

Die Erfindung betrifft eine Hubstange zur Verbindung des Unterlenkers einer Dreipunktanbauvorrichtung eines Traktors mit dem Hubarm des Traktors, mit ersten Anschlußmitteln zur Verbindung mit dem Hubarm des Traktors und zweiten Anschlußmitteln zur Verbindung mit dem Unterlenker des Traktors, mit einem Gehäuse und einem dazu in einer Bohrung entlang einer Längsachse verstellbar aufgenommenen Stangenelement, welche jeweils einem der Anschlußmittel zugeordnet sind, mit Mitteln zum Festsetzen des Stangenelementes zum Gehäuse auf eine fixe Länge, welche einen Steckbolzen und eine Steckbohrung im Gehäuse, die in der einen Richtung, sowie Anschläge am Gehäuse und am Stangenelement, die in der anderen Richtung wirksam sind, umfassen, und mit Mitteln zur Einstellung der fixen Hubstangenlänge,die eine Gewindeverbindung umfassen.The invention relates to a lifting rod for connecting the lower link of a three-point hitch of a tractor to the lifting arm of the tractor, with first connecting means for connecting to the lifting arm of the tractor and second connecting means for connecting to the lower link of the tractor, with a housing and one in a bore along a longitudinally adjustable rod element, each of which is assigned to one of the connecting means, with means for fixing the rod element to the housing to a fixed length, which has a plug pin and a plug hole in the housing, which in one direction, and stops on the housing and on the rod element, which operate in the other direction, and with means for adjusting the fixed lifting rod length, which comprise a threaded connection.

Eine solche Hubstange ist in der US 30 56 458 beschrieben. Das Gehäuse weist eine an seinem offenen Ende, aus dem das Stangenelement austritt, angebrachte Führungshülse auf, die zur Führung des Stangenelementes dient. An dem in das Gehäuse eintauchenden Ende des Stangenelementes ist eine weitere Führungshülse angebracht. Das Stangenelement ist mit einem Gewindeabschnitt in eine Gewindebohrung der Führungshülse eingeschraubt. Hierdurch ist die fixe Länge der Hubstange einstellbar, indem das Stangenelement zur Führungshülse verdreht wird. Die dem Stangenelement zugeordnete Führungshülse ist zwischen der dem Gehäuse zugeordneten Führungshülse und dem durch Bohrungen des Gehäuses hindurchsteckbaren Steckbolzen festlegbar. Um eine Schwimmstellung zu erreichen, ist der Steckbolzen aus dem Gehäuse herauszuziehen, so daß das Stangenelement mit seinem in dem Gehäuse eintauchenden Ende und diesem entlang der Längsachse verstellbar ist. Zur Einstellung der fixen Länge ist das dem Stangenelement zugeordnete Anschlußmittel in Form eines Gabelkopfes vom Unterlenker zu lösen. Danach kann das Stangenelement um die Längsachse gedreht werden. Voraussetzung dafür ist jedoch, daß die dem Stangenelement zugeordnete Führungshülse sich selbst nicht um die Längsachse dreht. Ferner besteht die Gefahr, daß im Betrieb beim Auftreten von Erschütterungen sich die Einstellung verändert, da die Führungshülse sich ungehindert auf dem Gewinde des Stangenelementes drehen kann.Such a lifting rod is described in US 30 56 458. The housing has a guide sleeve attached to its open end, from which the rod element emerges, which serves to guide the rod element. A further guide sleeve is attached to the end of the rod element that dips into the housing. The rod element is screwed into a threaded bore of the guide sleeve with a threaded section. In this way, the fixed length of the lifting rod can be adjusted by turning the rod element to the guide sleeve. The guide sleeve assigned to the rod element is between that assigned to the housing Guide sleeve and the plug pin that can be inserted through the bores of the housing. In order to achieve a floating position, the plug pin must be pulled out of the housing, so that the rod element, with its end immersed in the housing, can be adjusted along the longitudinal axis. To set the fixed length, the connecting means assigned to the rod element in the form of a fork head must be detached from the lower link. The rod element can then be rotated about the longitudinal axis. However, the prerequisite for this is that the guide sleeve assigned to the rod element does not itself rotate about the longitudinal axis. Furthermore, there is a risk that the setting changes when vibrations occur, since the guide sleeve can rotate freely on the thread of the rod element.

Der Erfindung liegt die Aufgabe zugrunde, eine Hubstange zu schaffen, bei der die Einstellung der fixen Hubstangenlänge ermöglicht wird, ohne daß eines der Anschlußmittel vom Traktor bzw. vom Hubarm des Traktors oder vom Unterlenker desselben gelöst werden mußte. Darüber hinaus soll gewährleistet sein, daß die einmal eingestellte Länge sich während des Gebrauchs nicht ändern kann.The invention has for its object to provide a lifting rod in which the adjustment of the fixed lifting rod length is made possible without one of the connecting means having to be released from the tractor or from the lifting arm of the tractor or from the lower link thereof. In addition, it should be ensured that the length once set cannot change during use.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Stangenelement zumindest an seinem aus dem Gehäuse herausgeführten Ende einen Bohrungsabschnitt mit einem Gewinde aufweist, in dem eine Gewindestange mit ihrem Außengewinde verstellbar einsitzt, die mit einem der Anschlußmittel verbunden ist, und wobei der Bohrungsabschnitt und die Gewindestange die Mittel zur Einstellung der fixen Hubstangenlänge bilden, daß das Stangenelement an seinem in das Gehäuse eintauchenden Ende mit einer Ausnehmung oder Bohrung versehen ist, durch welche der in die Steckbohrung des Gehäuses eingesteckte Steckbolzen hindurchragt und damit das Stangenelement zum Gehäuse festsetzt, und daß das Stangenelement ferner an diesem Ende zur Ausnehmung bzw. Bohrung um die Längsachse versetzt einen sich entlang der Längsachse erstreckenden Schlitz aufweist, in den der Steckbolzen nach entsprechender Verdrehung des Stangenelementes zum Gehäuse einsteckbar ist.This object is achieved in that the rod element has at least at its end led out of the housing a bore section with a thread, in which a threaded rod with its external thread is adjustably seated, which is connected to one of the connection means, and wherein the bore section and the threaded rod the means for adjusting the fixed lifting rod length form that the rod element is provided at its end which dips into the housing with a recess or bore through which the plug pin inserted into the plug bore of the housing protrudes and thus fixes the rod element to the housing, and that the rod element furthermore, offset at this end to the recess or bore around the longitudinal axis, has a slot extending along the longitudinal axis, into which the plug pin according to the corresponding Rotation of the rod element to the housing can be inserted.

Von Vorteil bei dieser Ausbildung ist, daß lediglich durch Entfernen des Steckbolzens es ermöglicht wird, das Stangenelement am vom Unterlenker gehaltenen Anschlußmittel, welches die Gewindestange aufweist, zu verdrehen, woraus eine Längenänderung resultiert. Wird der Steckbolzen eingesteckt, so ist die Länge für beide Positionen, in denen das Stangenelement gegenüber dem Gehäuse festgelegt werden kann, nicht mehr veränderbar. Das Stangenelement ist mittels des Steckbolzens sowohl in der Starrstellung als auch in der Schwimmstellung verdrehbar zum Gehäuse gehalten.The advantage of this design is that only by removing the plug pin it is possible to turn the rod element on the connection means held by the lower link, which has the threaded rod, which results in a change in length. If the plug pin is inserted, the length can no longer be changed for both positions in which the rod element can be fixed relative to the housing. The rod element is rotatably held to the housing both in the rigid position and in the floating position by means of the plug pin.

Darüber hinaus ist eine einfache Handhabung zur Umstellung von Schwimm- auf Starrstellung und umgekehrt möglich. Schließlich ergeben sich aufgrund der Anordnung kurze Baulängen. Die Länge des Schlitzes ist so bemessen, daß die gewünschte Axialverstellung von Stangenelement zum Gehäuse entlang der Längsachse erreicht wird. Vorzugsweise sind die Ausnehmungen und der Schlitz zu der in das Gehäuse eintauchenden Stirnfläche des Stangenelementes offen. Das Stangenelement kann aus einem Vollmaterial bestehen, das an dem Ende, in dem die Gewindstange einsitzt, hohlgebohrt ist oder, um eine möglichst leichte Ausführungsform zu erzielen, aus einem Rohr gestaltet sein.In addition, easy handling for switching from floating to rigid position and vice versa is possible. Finally, the overall arrangement results in short overall lengths. The length of the slot is dimensioned such that the desired axial adjustment from the rod element to the housing is achieved along the longitudinal axis. The recesses and the slot are preferably open to the end face of the rod element which dips into the housing. The rod element can consist of a solid material which is hollow drilled at the end in which the threaded rod is seated or, in order to achieve the simplest possible embodiment, can be made from a tube.

Ferner ist zur Bewegungsbegrenzung in Auszugsrichtung des Stangenelementes aus dem Gehäuse dem Stangenelement mindestens ein Führungsring zugeordnet. Dieser ist unmittelbar zur Abstützung an einem weiteren dem Gehäuse zugeordneten Anschlag vorgesehen. Es ist jedoch auch möglich, zur Abstandsüberbrückung die Abstützung des dem Stangenelement zugeordneten Führungsringes an einer Buchse vorzunehmen, die dem Anschlag des Gehäuses vorgeschaltet ist. Vorzugsweise sind dem Stangenelement zwei Führungsringe zugeordnet, die auf diesem zueinander beabstandet angebracht sind. Hierbei können die Führungsringe jeweils in einer Richtung verschiebbar auf dem Stangenelement angebracht sein und in der anderen Richtung durch Sicherungsringe festgelegt werden. Die Anordnung ist vorzugsweise so getroffen, daß die Führungsringe jeweils durch einen Sicherungsring am Gehäuse bzw. am Stangenelement in entgegengesetzten Richtungen wirkend festgelegt sind. Zwischen den beiden Führungsringen ist eine Druckfeder abgestützt. Diese dient dazu, die Führungsringe bei Starr- und Schwimmstellung in Anlage zu den Sicherungsringen zu halten.Furthermore, at least one guide ring is assigned to the rod element in order to limit the movement in the pull-out direction of the rod element from the housing. This is provided directly for support on a further stop assigned to the housing. However, it is also possible, in order to bridge the distance, to support the guide ring assigned to the rod element on a bushing which is connected upstream of the stop of the housing. Preferably, two guide rings are assigned to the rod element, which are attached to it at a distance from one another. In this case, the guide rings can each be slidably mounted on the rod element in one direction and can be fixed in the other direction by retaining rings. The The arrangement is preferably such that the guide rings are each fixed in opposite directions by a locking ring on the housing or on the rod element. A compression spring is supported between the two guide rings. This serves to hold the guide rings in rigid and floating positions in contact with the circlips.

Alternativ ist es möglich, die Führungsringe fest mit dem Stangenelement zu verbinden.Alternatively, it is possible to firmly connect the guide rings to the rod element.

Eine besonders günstige Gestaltung ergibt sich, wenn das Stangenelement als Rohr ausgebildet ist.A particularly favorable design results if the rod element is designed as a tube.

Um das Verdrehen des Stangenelementes zur Einstellung der fixen Hubstangenlänge zu erleichtern, ist an dessen Außenseite eine Lasche angebracht. Diese steht, bezogen auf die Längsachse, radial ab. Üblicherweise ist eines der Anschlußmittel als Kugelgelenk und das andere als Anschlußgabel ausgebildet.In order to facilitate the turning of the rod element to adjust the fixed lifting rod length, a tab is attached to the outside. This protrudes radially in relation to the longitudinal axis. Usually one of the connection means is designed as a ball joint and the other as a connection fork.

Aus Figur 1 ist der Traktor 1 mit einem an seinem Heck mit einem Ende schwenkbar angebrachten Unterlenker 2 ersichtlich. Parallel zu dem sichtbaren Unterlenker 2 ist ein weiterer Unterlenker angebracht. Oberhalb und zwischen diesen beiden ist der Oberlenker 5 mit einem Ende am Traktorheck schwenkbar angelenkt. Unterlenker 2 und Oberlenker 5 dienen zur Anbringung eines Gerätes an den Traktor 1. Zur Bewegung des anzuhängenden Gerätes ist der Unterlenker 2 mittels der Hubstange 4 an den Hubarm 3 angelenkt. Der Hubarm 3 ist mit einem Kraftantrieb verbunden, über den er heb- und senkbar ist. Über die Hubstange 4 wird damit auch der Unterlenker 2 gehoben oder gesenkt. Zur Verbindung der Hubstange 4 mit dem Unterlenker 2 dient eine Anschlußgabel 6. Ferner ist die Hubstange 4 an den Hubarm 3 mittels eines Kugelgelenkes 7 angeschlossen.FIG. 1 shows the tractor 1 with a lower link 2 which is pivotally attached at its rear at one end. Another lower link is attached parallel to the visible lower link 2. Above and between these two, the upper link 5 is pivoted at one end on the rear of the tractor. Lower link 2 and upper link 5 are used to attach a device to the tractor 1. To move the device to be attached, the lower link 2 is articulated to the lifting arm 3 by means of the lifting rod 4. The lifting arm 3 is connected to a power drive, via which it can be raised and lowered. The lower link 2 is thus raised or lowered via the lifting rod 4. A connecting fork 6 is used to connect the lifting rod 4 to the lower link 2. The lifting rod 4 is also connected to the lifting arm 3 by means of a ball joint 7.

Die Hubstange 4 ist in Figur 2 in vergrößertem Maßstab im Verhältnis zur Figur 1 in der Seitenansicht dargestellt. Die Hubstange 4 umfaßt ein Stangenelement 11, das die Anschlußgabel 6 trägt, und das Gehäuse 8, an dem das Kugelgelenk 7 befestigt ist. Das Stangenelement 11 ist in dem Gehäuse 8 entlang der Längsachse 17 verstellbar. Es kann jedoch auch über einen Steckbolzen 24, der in eine Bohrung 23 des Gehäuses 8 eingesteckt ist und mit einem Ende aus diesem herausragt, auf eine fixe Länge blockiert werden. Die fixe Länge der Hubstange kann darüber hinaus mittels des Stangenelementes 11, das mit der Anschlußgabel 6 über eine Gewindeverbindung verbunden ist, durch Verdrehen des Stangenelementes 11 durch Angriff an die Lasche 18 eingestellt werden. Dies ist im Zusammenhang mit Figur 3 noch näher beschrieben.The lifting rod 4 is shown in Figure 2 on an enlarged scale in relation to Figure 1 in a side view. The lifting rod 4 comprises a rod element 11, which carries the connecting fork 6, and the housing 8, to which the ball joint 7 is attached. The rod element 11 is adjustable in the housing 8 along the longitudinal axis 17. However, it can also be blocked to a fixed length by means of a plug pin 24, which is inserted into a bore 23 of the housing 8 and protrudes from it with one end. The fixed length of the lifting rod can also be adjusted by means of the rod element 11, which is connected to the connecting fork 6 via a threaded connection, by rotating the rod element 11 by attacking the tab 18. This is described in more detail in connection with FIG. 3.

Aus Figur 3 ist ersichtlich, daß die Anschlußgabel 6 eine Gewindestange 9 trägt, die mit einem Gewinde in eine Gewindebohrung 10 des rohrförmig gestalteten Stangenelementes 11 eingeschraubt ist. Das Stangenelement 11 ragt in die Bohrung 21 des Gehäuses 8 axial hinein. Ausgehend von der Stirnfläche 12 des Stangenelementes 11, die in die Bohrung 21 des Gehäuses 8 eintaucht, ist eine zur Stirnfläche 12 hin offene Ausnehmung 13 angebracht, die dem Querschnitt des Steckbolzens 24 angepaßt ist und quer zur Längsachse 17 verläuft. Dem Stangenelement 11 sind zwei Führungsringe 15, 16 zugeordnet. Diese sind im Abstand zueinander angeordnet. Der Führungsring 15 sitzt auf der Außenfläche des Stangenelementes 11 auf und stützt sich in Richtung auf das Kugelgelenk 7 zu gegen einen Sicherungsring 22 ab. Der zweite Führungsring 16 ist zum offenen Ende des Gehäuses 8 hin auf der Außenfläche des Stangenelementes 11 angeordnet und stützt sich in Richtung zur Anschlußgabel 6 hin gegen den Sicherungsring 22', der in eine Nut in der Gehäusebohrung 21 eingreift, ab. Zwischen beiden ist eine Druckfeder 19 abgestützt. Diese ist koaxial um das Stangenelement 11 herum angeordnet. Zwischen den beiden Führungsringen 15, 16 ist eine Buchse 20 angeordnet. Bei Einleitung einer Kraft in Richtung F1 auf die Anschlußgabel 6 wird diese über die Gewindestange 9 auf das Stangenelement 11 und von dem Sicherungsring 22 auf den Führungsring 15 und von diesem über die Buchse 20 und den Führungsring 16 auf den Sicherungsring 22' und von diesem in das Gehäuse 8 und das Kugelgelenk 7 übertragen, so daß eine Verlängerung der Hubstange nicht möglich ist. Bei Aufbringung einer Kraft F2 in der dazu entgegengesetzten Richtung wird diese über die Anschlußgabel 6 auf die Gewindestange 9, das Stangenelement 11 und von diesen über den Steckbolzen 24 auf das Gehäuse 8 und das Kugelgelenk 7 übertragen, so daß auch eine Verkürzung der Hubstangenlänge nicht möglich ist. Darüber hinaus ist auch eine Betätigung des Stangenelementes 11 im Sinne einer Verdrehung um die Längsachse 17 nicht möglich, da bei eingebauter Hubstange entsprechend Figur 1 die Anschlußgabel 6 und das Gehäuse 8 nur im Rahmen der Bewegungsmöglichkeit des Kugelgelenkes 7 zueinander verdrehbar sind. Das Stangenelement 11 wird durch den Steckbolzen 24, der in die Ausnehmung 13 eingreift, unverdrehbar zum Gehäuse 8 gehalten. Somit ist auch keine Verstellung auf der Gewindestange 9 möglich. Das rohrförmige Stangenelement 11 ist ausgehend von der Stirnfläche 12 mit einem Schlitz 14 versehen, der 90° zur Ausnehmung 13 um die Längsachse 17 versetzt angebracht ist. Zur Bewegung von Stangenelement 11 und Gehäuse 8 in eine Stellung, in der die Starrstellung, wie sie aus Figur 3 ersichtlich ist, aufgegeben ist und eine axiale Verstellung von Stangenelement 11 und Gehäuse 8 zueinander entlang der Längsachse möglich ist, ist zunächst der Steckbolzen 24 aus der Ausnehmung 13 und der Steckbohrung 23 des Gehäuses 8 herauszuziehen. Anschließend erfolgt eine Verdrehung des Stangenelementes 11 durch Angriff an die Lasche 18 um 90° in die aus Figur 4 ersichtliche Position. Danach kann der Steckbolzen 24 in die Bohrung 23 des Gehäuses 8 wieder eingesteckt werden und den Schlitz 14 passieren, um auf der anderen Seite aus der Bohrung 23 des Gehäuses 8 auszutreten. Bei dieser Position ist bei Einleitung einer Kraft in Richtung F2 gemäß Figur 3 auf die Anschlußgabel 6 eine Verkürzung der Hubstangenlänge insofern möglich, als das Stangenelement 11 weiter in das Gehäuse 8 hinein bewegt werden kann, bis je nach Bemessung dessen Stirnfläche 12 entweder zur Anlage am Boden 25 kommt oder das Ende des Schlitzes 14 zur Anlage an den Steckbolzen 24 gelangt. In einer der Richtung F1 entsprechenden Kraftaufbringung auf die Anschlußgabel 6 ergeben sich dieselben Verhältnisse, wie im Zusammenhang mit Figur 3 beschrieben.From Figure 3 it can be seen that the connecting fork 6 carries a threaded rod 9 which is screwed with a thread into a threaded bore 10 of the tubular rod element 11. The rod element 11 projects axially into the bore 21 of the housing 8. Starting from the end face 12 of the rod element 11, which dips into the bore 21 of the housing 8, a recess 13 is provided which is open towards the end face 12 and which is adapted to the cross section of the plug pin 24 and extends transversely to the longitudinal axis 17. Two guide rings 15, 16 are assigned to the rod element 11. These are spaced from each other. The guide ring 15 is seated on the outer surface of the rod element 11 and is supported in the direction of the ball joint 7 against a locking ring 22. The second guide ring 16 is arranged towards the open end of the housing 8 on the outer surface of the rod element 11 and is supported in the direction of the connecting fork 6 against the locking ring 22 ', which engages in a groove in the housing bore 21. A compression spring 19 is supported between the two. This is arranged coaxially around the rod element 11. A bushing 20 is arranged between the two guide rings 15, 16. When a force is applied in the direction F1 to the connecting fork 6, this is applied via the threaded rod 9 to the rod element 11 and from the locking ring 22 to the guide ring 15 and from this via the bushing 20 and the guide ring 16 to the locking ring 22 'and from this in the housing 8 and the ball joint 7 transmitted, so that an extension of the lifting rod is not possible. When a force F2 is applied in the opposite direction, this is transmitted via the connecting fork 6 to the threaded rod 9, the rod element 11 and from this via the plug pin 24 to the housing 8 and the ball joint 7, so that a shortening of the lifting rod length is also not possible is. In addition, actuation of the rod element 11 in the sense of a rotation about the longitudinal axis 17 is not possible, since when the lifting rod is installed according to FIG. 1, the connecting fork 6 and the housing 8 can only be rotated relative to one another within the scope of the movement of the ball joint 7. The rod element 11 is held non-rotatably relative to the housing 8 by the plug pin 24, which engages in the recess 13. Thus, no adjustment on the threaded rod 9 is possible. Starting from the end face 12, the tubular rod element 11 is provided with a slot 14, which is offset at 90 ° to the recess 13 about the longitudinal axis 17. For moving the rod element 11 and the housing 8 into a position in which the rigid position, as can be seen from FIG. 3, is given up and an axial one Adjustment of rod element 11 and housing 8 relative to one another along the longitudinal axis is possible first of all by pulling the plug pin 24 out of the recess 13 and the plug bore 23 of the housing 8. The rod element 11 is then rotated by attacking the tab 18 by 90 ° into the position shown in FIG. 4. The plug pin 24 can then be reinserted into the bore 23 of the housing 8 and pass through the slot 14 in order to emerge from the bore 23 of the housing 8 on the other side. In this position, when a force is applied in the direction F2 according to FIG. 3 to the connecting fork 6, a shortening of the lifting rod length is possible insofar as the rod element 11 can be moved further into the housing 8 until, depending on the dimensioning, its end face 12 either contacts the system Bottom 25 comes or the end of the slot 14 comes to rest against the socket pin 24. The same conditions as described in connection with FIG. 3 result in the application of force to the connecting fork 6 corresponding to the direction F1.
